Meanwhile, Governor Gavin Newsom asked a court to put an emergency stop to the military helping federal immigration agents, with some guardsmen now standing in protection around agents as they carried out arrests.

By Brad Brooks, Phil Stewart, Idrees Ali and Dietrich Knauth LOS ANGELES (Reuters) -Hundreds of U.S. Marines arrived in the Los Angeles area on Tuesday under orders from President Donald Trump, as the city's mayor declared a curfew for parts of the downtown area and police arrested 197 people in a fifth day of street protests.

President Donald Trump has built his presidency around stretching the bounds of presidential authority, and his response to protests over an immigration crackdown in Los Angeles is no exception.

Six Americans tell the BBC that there's clearly a problem in Los Angeles - they just don't agree with who's at fault.

Protests in Los Angeles appeared to quiet overnight, but new ones are popping up in other cities. Trump has deployed more than 4,000 National Guard troops and 700 Marines to the protests.

The California Governor has sued the U.S. President over the mobilization of the National Guard, calling it “an unmistakable step toward authoritarianism.”

Tensions flared in Los Angeles late Monday. On Tuesday, teams worked to scrub away, cover up or fade out protesters' graffiti.
